1. 20 Sep 2007Paul Dauncey1 CALICE beam tests Fantastically successful beam test at CERN this summer Yoshi will give a report on this shortly UK easily pulled its weight in terms of shifts so thanks to those who helped Many thanks to Fabrizio: as co-run coordinator he did an amazing job Most impressive number: we took >80% of available beam as beam data World tour continues in FNAL in 2008 Equipment currently at DESY for repair Will arrive at FNAL in Feb 2008 (hopefully in one piece) Si-W ECAL, AHCAL, TCMT for ~two months (low E, cross-check) Sc-W ECAL, AHCAL, TCMT for ~three months (full program) Si-W ECAL, DHCAL, TCMT for ~three months (full program) But all depends on production of ECAL and DHCAL modules Si-W really should be complete (this time!) and Sc-W seems under control DHCAL in particular now seems unlikely to be complete before end 2008

2. 20 Sep 2007Paul Dauncey2 LCWS R&D Review Draft report only available privately so far But thought to be quite close to final; may be released at ALCPG Generally, extremely positive (about CALICE at least!) “The committee is impressed by the exceptional quality and the enormous collaborative effort” “The test-beam program…is of the highest relevance for the design and construction of an ILC detector” “Groups unable to test…on this scale will have little chance of being selected as a technology for the final ILC detectors” But also a few warnings, some relevant to the UK “The collaboration needs to define a procedure and goals for the test beam data in order to aid the convergence on final detector choices” “More effort is needed to understand the full potential [of MAPS]” “The [SiD ECAL] beam tests should be prepared and performed in close collaboration with CALICE”

3. 20 Sep 2007Paul Dauncey3 Detector concepts Clearly an important time in this area LOIs (LsOI?) due towards end of 2008, EDRs due in 2010 We will have to get more involved Individual groups will decide which of ILD or SiD to get involved in CALICE-UK work would ideally be presented in both; the R&D should be concept-independent to a large extent The ILD meeting tomorrow is a step in this process; please stay on for this if you can Probable UK will have joint LCFI/CALICE/SiD/ILD meetings Forum to pool resources, results, technical software know-how, etc, to make best use of the effort we have available Allows the UK to make an informed choice about detector performance Potentially these meeting could be every ~two weeks Decisions on the details to be made at LCUK in Liverpool next week
